The Renewable Energy Crisis
Renewables are not working due to:
1. Intermittency:

What CAES Is
What it is
Take in surplus electricity
Use it to pump compressed air into a salt cavern
When demand exceeds supply, regenerate electricity
What it does
Store gigawatt hours per installation
Match supply with demand
The only technology that can, grid scale, today or soon
Proven and working reliably since 1978
But only 42-50% efficient

What We Have
3 patents pending using existing, proven technologies to increase
efficiency to 70-85% – and the threshold for viability is around 60%;
5 more patents written, for even greater efficiency;
 2 locations in the North West with salt caverns and local support;
 1-3GWh storage per installation, generating min. 250-500MW;
 Outstanding expertise within our team;
 A market for generating min. 27GW of peak (i.e. premium rate)
electricity and storing 2.5TWh in the UK alone;
 Ability to replicate throughout the country and world;
 A very strong business case based on conservative figures, with strong
profitability from a single installation.
